CORSAIR RM850e vs Lian Li Edge Series-850W Full Modular Power Supply-80 Plus Platinum-ATX 3.0

Price Comparison

When it comes to price, the CORSAIR RM850e is more affordable at C$184.99 compared to the Lian Li Edge Series, which retails for C$195.95. This difference of C$10.96 might seem minor, but for budget-conscious consumers, every dollar counts. Both power supplies are positioned in the premium segment of the market, making their pricing crucial in the decision-making process. While the Lian Li offers some advanced features, the cost-effectiveness of the CORSAIR cannot be overlooked, especially for users looking to maximise their spending.

Efficiency Ratings

The Lian Li Edge Series boasts an impressive 80 PLUS Platinum efficiency rating, while the CORSAIR RM850e is certified under the Intel ATX 3.1 standard but does not specify an efficiency rating. The Platinum rating indicates that the Lian Li model operates at a higher efficiency, translating to less energy waste and potentially lower electricity costs over time. This characteristic could make it more appealing for users who heavily rely on their PCs for extended periods, as the savings on energy bills may offset the higher upfront cost.

Modular Design

Both power supplies feature fully modular designs, allowing users to connect only the cables they need, which helps reduce clutter and improve airflow within the case. However, the Lian Li Edge Series includes a built-in USB expansion hub with four internal USB 2.0 headers, adding a layer of functionality that the CORSAIR RM850e lacks. This feature could be particularly beneficial for users with multiple devices or peripherals that require USB connectivity, making the Lian Li a more versatile option in this regard.

Cooling Solutions

Cooling is crucial for maintaining optimal performance, and both power supplies employ effective cooling mechanisms. The CORSAIR RM850e features a 120mm rifle bearing fan with a specially calculated fan curve to minimise noise, even under full load. The Lian Li Edge Series also uses a 120mm fan, which operates in a fanless mode under low loads, enhancing silent operation. While both options are designed to keep noise levels down, the Lian Li’s ability to run fanless under certain conditions could provide an edge for users prioritising a quiet computing environment.

Compatibility

Compatibility can be a defining factor for many users. The CORSAIR RM850e is Intel ATX 3.1 certified, making it a robust choice for modern builds, including support for PCIe 5.1 platforms. The Lian Li Edge Series is also ATX 3.0 compliant, ensuring it meets current standards. However, it comes with a notable caution: if installed in a non-dual chamber case, users must ensure that their case height does not exceed 400mm. This limitation could pose compatibility challenges for some users, particularly those with certain case designs.

Performance Under Load

Both power supplies are rated for a maximum DC output of 850W, suitable for high-performance builds. The CORSAIR RM850e is designed to withstand transient power excursions from GPUs, making it reliable during peak demand situations. The Lian Li Edge Series, while also capable of delivering 850W, includes advanced copper soldered terminals that enhance its performance reliability. This could be a deciding factor for users with high-end graphics cards that draw significant power during intensive tasks like gaming or rendering.

Build Quality

In terms of build quality, both power supplies are constructed with durability in mind. The CORSAIR RM850e utilises 105°C-rated capacitors, ensuring stable and reliable power delivery over time. The Lian Li Edge Series, on the other hand, is made from steel and features an L-shape design specifically for dual chamber cases, potentially enhancing airflow. While both manufacturers are reputable in the industry, the materials and design considerations of the Lian Li might resonate more with users who prioritize aesthetics and structural integrity in their builds.

Which should you buy?

Ultimately, the choice between the CORSAIR RM850e and the Lian Li Edge Series comes down to specific user needs and preferences. If you're looking for a more budget-friendly option with solid performance and quieter operation, the CORSAIR RM850e at C$184.99 is a compelling choice. Conversely, if you value higher efficiency, additional USB connectivity, and advanced cooling capabilities, the Lian Li Edge Series at C$195.95 may justify the extra expense. Assessing your priorities—whether it's price, efficiency, or unique features—will lead you to the best decision for your power supply needs.
